Police began investigating an incident of allegedly causing grievous bodily harm which happened at about 12.15am.

Residents living in the small terrace said after the incident that they were too frightened to speak up about issues relating to a house where the incident took place.

Speaking anonymously, they said there were people coming and going from the property all times of the day and night which resulted in noise and arguments.

One resident, who did not want to be named for fear of repercussions, said: “We see so many comings and goings. It is obvious what is going on – they are not going there for a cup of tea are they?

“You hear noises, shouting, arguments. One day someone was running up and down the street and I shouted at him to be quiet.”

Residents said they saw an ambulance and police cars outside and officers with police dogs searching the area.

“We thought the house was being raided at first there was so much going on,” said one resident.

A Devon and Cornwall Police spokesman said: "A man in his thirties was stabbed in the back and the chest. Ambulance attended and his injuries are not believed to be life-threatening.”

Leaflets were dropped through neighbours' doors by officers requesting anyone with information in relation to the assault to get in touch.

But another resident said people refused to speak out.

“People don’t say anything," they said. "We keep ourselves to ourselves. We don’t want any repercussions. If someone is capable of doing that, they don’t care who they will get. People are frightened.”

This week the police said they were not appealing for any further information as enquiries were in hand.
